To all whom it may concern.' p Be it known that L WALTER JOHNSON, a citizen of ythe United States, residing at North Loup, in the county of Valley and State of Nebraska, have invented certain new and useful Improvements in a Purifying Apparatus for Liquid Hydrocarbon, of which the' following is a specification.

'This inventionv relates to an apparatus for purifying liquid hydrocarbon, and has for its object to provide an apparatus by means of which all grades of mineral oil.

may be conveniently` and effectively treated for` this purpose. y

The invention consists of the novel construction, -combination and arrangement of parts as 'described herein' and claimed, and.

as illustrated in the accompanying drawinv, wherein the single figure is a view in side elevation. partly in section, of an apparatus showing one embodiment ofthe invention.

I provide a container 1, provided inidway between its ends with a partition 2, to provide an upper compartment 3 and a lower compartment e, said partition having an aperture 5 formed therein, and being provided on its upper sidel with a sleeve 6 circumscribing said aperture.

The'partition 2, preferably, is imperorate with the exception of its aperture 5. Below and near said partition" is a distributingre oeptacle 7 having an exit port 8 and a plu- Itality of apertures 9, formed in its bottom.

Numeral 10 indicates a foraminous partition disposed neary the bottom of the container, and thereby forming a: compartment 11; and communicating with this compartment is a drain pipe 12, provided with a valve 13. u y o ,In the upper compartment is a` pipe-coil 14 havin a lower, rectilinear part a traversin the s eeve 6 to communicate with the distriuting-receptacle 7, said part a being provided with a hood 15 overhanging the sleeve. l

Numeral 16 indicates a tank for containin liquid hydrocarbon under'pressure ,and de ivered thereto by the supply pipe 17, said pipe being provided with a valve'17, and the` pressure being suicient in degree to cause said liquid to be conducted' by the pipex18 to the pipe' coil 14, the pipe 1 being provided with a valve 19. i.

.Numeral 20 indicates a discharge port for -the container 1, said being disposed l above and near the partition 2 and in communication with a conducting pipe 21, said last named pipe having a spiral part b disposed within a condensing reservoir 22, its discharge terminal being?, provided with a valve 23. Numeral 24 indicates an intake pipe for the reservoir, this ipe being provided with a valve 25, said) reservoir also being provided with a discharge pipe 26 having .a valve 27. v

As thus described, it will be understood that if the valves 17', 19 and 23 are open, liquid hydrocarbon will enter the distributing-ieceptacle 7 and will pass through the apertures 9 of said receptacle; and during' operation, on account of the control provided yby the valves, the supply of liquid hydrocarbonjfor the container 1, is limlted to that part below and adjacent to the distributing-receptacle. y Y' In order that the liquid hydrocarbon may be effectively and conveniently purified, it isaccomplished by vaporization by use of heating devices within and wholly ,se arated from the container, and consisting o a plurality of electrical resistant'coils c, these preferably being disposed substantially parallel with reference to each other within the lower compartment in line with the apertures 9 of the distributing-receptacle, said resistant coils 'preferably being employed in pairs, the upper part of each pair being mounted upon a pair of insulated arms d, with which the distributing-receptacle is provided.

The partition 10 is.provided,.to project below its bottom, with a plurality of insulating blocks e and It, these being arranged in pairs for a mounting of the metallic plugs 7c which provide a mounting for the lower ends of the resistant coils.

At m is indicated an annular electrical conductor which is disposed adjacent to thev cylindrical wall of the container,.said con ductor being suitably secured to the lower ends 'of 'the insulating blocks e, said conductor m being in contact with the metallic plugs 7c of said blocks e, and at n is indicated a second annular electrical conductor which is disposed inwardly and adjaf centto the conductor m, said conductor n', bein secured to the lowerends of the insulating blocks h, said conductor n bein in contact with the metallic plugs la of sai insulating blocks v Numeral 28 indicates a sleeve upon:n which the partition 10 is disposed. Any suitable number olE resistance coils may be employedand they may be energized by any adequate source oli electrical supply` an elect-ric battery 29 being shown for this purpose, its conductor Slt). oll one polarity. being in electricalcontact w'ith the endless/ conductor 7n. and the conductor Bl. ot opposite polarity. being in electrical Contact with the cndless conductor n.

While l have descril'ied the foregoing elements in detail, l do not wish to be understood as limiting mjsel't' in this respect, nor to tornisize, proportion of parts, nor nia,- terial to be employed. since the scope ot the invention is determined by the appended claims.

As stated above. any desired number of electrically energized resistant coilsrIn-ay be employed. and ou account of their arrangement and the proportion of parts. an intense heat may be generated. During operation. 'for obtaining the best results, the valve 13 should remain open, and by adjustments of the other valves mentioned, the supply otl liquid hydrocarbon within the compartment it should be maintained from one-halt' to two-thirds tilled. The liquid lrvdrocarbon will bel delivered to the lower ctnnpart-ment by passing through the apertures tl ot the distrihitting-receptacle, and moving downward by gravity upon the resistant coils.

The intense degree ot,l1\at will cause the liquid contents of the lower receptacle to be vaporized, the heated vapor moving upwardly through the ports 8 and 5 to the npper compartment 3, a part ot the heat being absorbed by the pipe-coil li. which. causes the cont its ot said pipe-coil to become heated ready tor deliver) to the distributing receptacle, the condensed parts on said coil 14 being prevented from moying downwardly within the sleeve C b v the hood l5.

The vaporizcd hydrocarbon. in this partly condensed condition, will then pass to the spiral part I) within the condensing reservoir 22 by passing the port 20 and conducting pipe 21. t will thus be seen that the parts employed are, few and may be economically manufactured, and it will be appreciated that the pipe coil 14 could be dispensed with, but since it utilizes the heat, it is o't advantage.

By passing water at a low temperature through the reservoir, the vaporized hydrocarbon may be condensed, the product being discharged through the valve 23, the large per cent of water generally contained, in suspended torni, in mineral oil, when un dergoing treatment in the container, as described, being subjected to a `tull white heat and being decomposed into an osg/igen and hydrogen gas.

incassa in the oil and is isolated frointhe walls ot the container. the heat is applied economi-y cally and without wasn; also. it 4is considered that the parts `operate autoinatically, or substantially so, requiring only a `limited attention ot' an operator.

lt will be understood that the residue oit the product passes the valve lil. which, as stated, remains open during operation, the

-residue moving to the compartment `lit through apertures fr,
